the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.

types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation.

an ammonoid that belongs to the order Ammonitida, typically having elaborately frilled suture lines.

a calcareous mound built up of layers of lime-secreting cyanobacteria and trapped sediment, found in Precambrian rocks as the earliest known fossils, and still being formed in lagoons in Australasia.

a fossil of a footprint, trail, burrow, or other trace of an animal rather than of the animal itself.

a fossil that is useful for dating and correlating the strata in which it is found.
